Since COB's rise to power in the early 1980s, there has not been one mention of the PRD either by him or anyone else in upper management. In fact, the only reference to it at all is an “HCOB” written in 1991 (five years after LRH’s death) which makes Key to Life and the Life Orientation Course prerequisites to the PRD.  (HCOB 24 April 1991, Modification of the Primary Rundown;
Tech Vol. XIII, p. 502)

The Primary Rundown has been eliminated from the training line-up. It is no longer available at any org or mission on the planet.
